The strains of Amhrán na bhFiann echoed through Dublin's Convention Centre yesterday as more than 3,000 immigrants from over 120 countries became citizens of Ireland.

There was a carnival atmosphere at the ceremony, and moments of high exuberance. But the good cheer was interspersed with moments of solemnity - as each applicant swore loyalty to the Irish State before receiving their naturalisation certificates.

Retired High Court Judge Bryan McMahon and retired District Court Judge Paddy McMahon were presiding officers at four of the citizenship ceremonies.

Tánaiste Joan Burton and Minister of State for New Communities, Culture and Equality Aodhán Ó Ríordáin were also in attendance.
